Effects of Excessive Soil Phosphorus Accumulation on Loblolly Pine (Pinus taeda L.) Seedlings
… soils can accumulate extremely high extractable phosphorus (P) concentrations, sometimes over 1000 mg kg<sup>-1 </sup>of plant available P. Landowners report the conversion of these pastures to loblolly pine (<em>Pinus taeda</em> L.) plantations is often problematic, with poor seedling survival …

Factors influencing phosphorus losses in agroecosystems dominated by tile drainage
Phosphorus is an important macronutrient for crop production but phosphorus surpluses may be conveyed from diffuse sources to streams via surface runoff and artificial subsurface (perforated plastic pipes called tiles) drainage affecting the quality of receiving aquatic ecosystems. However, …

Legacy Nutrient Management and Remediation in Diverse Agricultural Watersheds
… water quality impairments persist due to the accumulation of legacy nutrients—phosphorus (P) stored in soils and nitrogen (N) stored in groundwater—that continue to be mobilized long after management changes are implemented. This dissertation evaluates the magnitude, persistence, uncertainty, …

Effects of Biosolids on Tall Fescue-Kentucky Bluegrass Sod Production and Soil Chemical and Physical Properties
… the 0.5X rates did not increase soil extractable phosphorus, while the 1.0X rates steadily increased soil extractable phosphorus at. The 1.0X and 1.5X biosolids rates increased soil organic matter content, but only the 1.5X rate of cake biosolids reduced soil bulk density and mineral matter export …

Effect of biofertilizers on phosphorus nutrition and grain yield of des chickpea (Cicer arietinum L.) grown in different agro-ecologies
… evaluated the biofertilizers’ effects on the phosphorus accumulation in the rhizosphere soil, the acid and alkaline phosphatase activity in the rhizosphere soil and, the two chickpea genotypes’ growth and yields under different environments. In 2019, three field experiments were conducted in …
